TYPE-WRITING MACHINE.

Specification of Letters IPatent. Patented Ngv, 28, 1911,

Application filed July 9, 1910. Serial Ito. 571,150.

' My invention relates to ribbon mecha-' nism for typewriting machinesandits object, generally stated, is to provide improved mechanism of theclass specified.

More specifically my invention has to do with the provision of improvedmimeograph devices wherebythe use of the ribbon may be dispensed with atpleasure when it is desired to write a stencil or mimeograph sheet orfor similar purposes.

Another object of the invention is to provide .means for varying thenormal position of the printing portion of a vibratory g ribbon incombination with means for vibrating said printing portion diiierent eX-tents from a plurality of normal positions.

To the above and other ends my invention consists in the features ofconstruction, com:

binations of devices and arrangements of parts hereinafter described andparticularly pointed out in the claims.

While my invention may be adapted to various styles of writing machinesI have shown it as applied to a Monarch typewriter. In the presentinstance I substitute for the usual stationary guide for the rib boncarrier, which guide is rigid on the frame, a two-piece guide, one piecepivoted on the other, said two-piece guide being associated with a novelform of ribbon carrier.

enabling the types to co-act directly with the work sheet or-stencilsheet.

My invention will be more particularly explained in connectionwith theaccompanying drawings, wherein- Figure 1 is a vertical front to rearsectional view of a typewriting machine embodying my invention, so muchonly of the machine being shown as is necessary to a clear understandingof said invention. Fig. 2 is a diagrammatic view showing parts of theprinting portion of a ribbon in the different positions to which thesame may be moved in the operation of my invention. Fig. 3 is aperspective view of my improved ribbon carrier or vibrator. Fig. 4 is aperspective view of the guide for said improved By manipulating theguide the carrier may i shown) having'the usual or suitable conbedisconnected at one point from the operof the ribbon carrier and theprinting portion of the ribbon which is within the con 3 trol of saidcarrier. Further, means are provided for varying at will the normal reilationshi between the o eratin lever and the actuating devices therefor,whereby the extent of movement of the operating lever and the consequentextent of movement of the ribbon carrier may be varied. As a rei sultthe ribbon carrier may be moved variable extents from one normalposition so as to present difl'erent fields of the ribbon pivoteduniversal bar frame, said frame ribbon carrier and also of part of thesupport for said guide. Fig. 5 is a sidr view partly in section showingthe ribbon carrier and its guide and part of the actuating andsupporting devices. Fig. 6 is a plan view partly in section of themechanism for varying the actuating devices for the operating lever.Fig. 7 is a fragmentary side view of a modified construction of ribboncarrier and operating lever.

As appears from Fig. 1 the main frame of the machine comprises a baseportion 1 from which rise posts 2 supporting a top plate 3. Key levers iare fulcrumed on a plate 5 in rear of the base, each key lever beingprovided with a restoring spring 6 and being connected with a type bar(not struction and mounting. The type bars when actuated are adapted 'tobe swung upward and rearward into cooperation with the front of a rollerplaten 7, diagrammatically illustrated herein. The platen is mounted ona carriage (not shown) which carrying a Universal bar 16 which underliesthe key levers 4.

A ribbon 17 is wound on horizontal spools 18, one at each side of themachine above the top plate and forward of the platen. Each spool issupported on a vertical shaft 19 which carries at its lower end abeveled pinion 20 meshing with. a beveled pinion 21 carried at theforward end of a horizontal ions 27 and 28. The spool turning or ribbonfeeding mechanism above described is like that of the Monarchtypewriting machine, but any other suitable ribbon feeding mechanism maybe employed if desired.

Midway between the ribbon spools the ribbon is threaded through avibratory ribbon carrier or vibrator designated as a whole as 29 andbest shown in Fig. 3. The head or upper portion of the ribbon carrier isor may beof ordinary construction comprising hooks 30 off-set laterallyfrom the side arms 31 the inner edges whereof arebent to provide grooves32. The ribbon passes from the hooks 3O behind the upper portions of thearms 31 and across the open space 33 be tween said arms. This space oropening 33 is usually called the type opening, the types passing throughit to cooperate with the ribbon and the platen. That portion of theribsecured together by rivets 36.

bon which bridges the type opening is commonly termed the printingportion of the ribbon. The depending part or stem of the ribbon carrier29 is provided with a central vertical slot 34 which forms two strips orfingers 35. These strips are doubled back on themselves and the twoplies or folds are The rear plies are bent or shaped to provide openingswhich frictionally hold cross pins 37 and 38 bridging the slot 34 andarranged one abovethe other and about it apart.

The ribbon carrier is supported and guided on a carrier guide which isbest shown in Fig. 4. Said guide comprises two parts 39 and 40. The part39 is provided with twoparallel upwardly extending fingers 41, the inneredges whereof are embraced by the grooves 32 in the ribbon carrier, theconstruction enabling the carrier to he slid up and down on the guide.The

lower side portions of the guide part 39 are bent rearwardly. formingcars 42 which embrace corresponding ears 43 pro ect1ng forwardly fromthe sides of the other guide part 40. This guide part is provided at itstop with a pair of books 44 which fit over thetop edge of the frameplate 45. A headed screw 46 (Figs. 1 and 5) secures the lower end oftheguide part 40 t0 the frame plate 45. Arranged between the head ofthis screw 46 and the guide part 40 is the usual cam member 47 whichcooperates with the usual card-guide 48 shown in Fig. 1 only. The guideparts 39 and 40 are pivotally connected together by a pin or rod 49which passes through the ears 42 and 43. The rod 49 also provides abearing for the swinging card guide 48 which as shown-in Fig. 1 eX-tends upward between the two guide parts and in rear of the ribboncarrier. A spring 50 (Fig. 4) is coiled around the rod 49 and its endsco-act with the guide parts. 39 and 40 to maintain them in the normalrelationship shown in Figs. 1 and 4 in which position stop faces 51formed at the front of the ears 43 contact with the rear face of thepart 39. By pressing rearward against the upper portions of the fingers41 the spring 50 may be overcome and the guide part 39 swung about thepivotal center 49. Since the guide part 39 controls the ribbon carrier29, the swinging movement of the guide part will be communicated to theribbon carrier. The swinging movement of the ribbon carrier and guidepart may also be caused. by pressure applied to the upper part of theribbon carrier, as well as to the guide part 39. This pivotal movementof the ribbon carrier is to enable one or another of the cross pins 37and 38 to be disconnected from the operating lever and the other crosspin to be connected therewith. The operating lever 52 is enlarged at itsforward end and formed with a horizontal open-mouthed slot 53 in whichthe cross pins are adapted to engage. The operating lever is fulcrumedat 54 to a lug depending from the top plate 3. As shown in Fig; 1 therear arm of the operating lever 52 is formed with an arcuate slot 56which is engaged by a lateral pin 57 y secured to the top of avertically-disposed link 58, the lower end of said link being pivotallyconnected with the arm 15 of the universal bar frame. It will beunderstood that when a key lever 4 is actuated the universal bar framewill be swung downward, lowering the link 58 and causing it to swing theoperating lever 52 on its fulcrum so as to raise the ribbon carrier andthe printing portion of the ribbon. It "ill be further understood thatthe extent of movement of the ribbon carrier may be varied by changingthe position of the actuating pin 57 in the slot 56,

this being accomplished by swinging the link 58 about its pivotalconnection with the arm 15. A draw spring 59 connects the links 14 and58 and tends constantly to swing the link 58 rearward about its pivot.The movements of the link 5% are controlled by a member 60 which isslidably mounted on the i the same time that it is fed lengthwise.

on the platen.

power shaft 26 and is connected to receive rotary movement from saidshaft. As shown in Fig. 6 the member 60 comprises three working faces(31, (S2 and (53 which are connected by cam surfaces. The faces 61 and 2are different in diameter but are both concentric with the shaft26,while the face (33 is eccentric thereto. A hub (34 extends rightwardfrom the member (50 and is formed with a circumferential groove 65.Loosely engaging .said groove is a forked arm 66 which is verticallydisposed and is provided atits upper end with a hub 67 which fits overand is fixed to the inner end of a slide rod 68. Said slide rod issupported on stationary lugs 69 and carries at its right-hand end avertical pin 70 which is engaged by the slotted arm of a bell cranklever 71 having a fixed fulcrum 72. A link 73 extending forward beneaththe top plate connects the other arm of the bell crank 71 with an arm ofa second bell crank 74 which is pivoted at 75 to the under side of thetop plate near the front of the machine and has an arm 76 extendingforward through a slot in the right-hand front plate 77. The forward endof the arm 7 6 is provided with a finger piece 78 by which the bellcrank 74 may be swung on its pivot, thereby operating through thedescribed connections to slide the rod 68 back and forth in its bearingsand vary the position of the member 60 lengthwise of the power shaft 26,thus bringing one or another of the working faces 61, 62 and 63 intocooperation with the link 58.

As is well understood the eccentric face (33 is employed when a uniformribbon is in use, so as to automatically and progressively vary thethrow of the ribbon carrier and obtain a crosswise feeding of the ribbonat the drawing, a two-color ribbon 17 is illustrated, said ribbon 17being divided lengthwise into fields m and n which may, for example. berespectively black and red. Vi'ith such a ribbon it is usual to set theactuating devices by employing the faces 61 and 62. lVhen the workingface 61 is in operation as shown in Figs. 1 and 6 the link 58 will bemaintained normally in the forward position, the pin 57 engaging withthe front end of the slot 56 near the fulcrum of the operating lever. Ifat this time the lower cross pin 37 is engaged with the operating lever52, then the printing portion of the ribbon wvill be normally maintainedin the position shown in Fig. l, and at printing operation will belifted so as to present the lower field a opposite the printing point 79Referring to Fig. 2 wherein the ribbon is represented by small parts orsections and the printing line is represented by the dotted line 37, p,the normal position of the ribbon corresponding with.

Fig. l is designated as a while the abnormal position in which the lowerribbon field is presented opposite the printing line is designated as (aIf the positioning member 60 be shifted by manipulating the finger pieceT8, so as to bring the working face (32 into use, then the link 58 willbe drawn back to the dotted line position in Fig. l and at printingoperation the ribbon carrier will be lifted to the 0 position of Fig. 2,thus presenting the upper ribbon field m to the types. It will beobserved that as thus far described the operation does not differmaterially from that of other two-color ribbon mechanisms heretoforeknown,

Suppose it be desired to dispense with the use of the ribbon entirely inorder that a stencil sheet may be printed or for some other reason, thenthe upper portion of the ribbon carrier is pressed rearward to thedotted line position of Fig. This results in swinging the lower crosspin 37 out of engagement with the slot 53 in the operating lever. Stillholding the ribbon carrier and its guide pressed in against the force ofthe spring 50, the carrier may be slid down on its guide until the uppercross pin 38 is opposite the slot 53 whereupon the carrier may bereleased and the spring will force the cross pin 38 into engagement withtheoperating lever. It will be seen that this change in connectionbetween the ribbon carrier and operating lever is effected withoutmoving or otherwise affecting the operating lever itself. By said changethe normal position of the printing portion of the ribbon is changedalso, being lowered from the a position of Fig. 2 to the positionindicated by the letter 02 in said figure. If now the link 58 be setnormally in the dotted line position of Fig. 1, it will operate when theprinting keys are actuated to raise the printing portion of the ribbononly to the position indicated by the letter 1 in Fig. 2 which is notfar enough to bring any portion of the ribbon opposite the printing lineon the platen. Consequently the types will move over the top edge of theribbon without touching the same and will cooperate directly with thework sheet.

Sometimes it is desirable to print a memorandum on the stencil sheetprior to I or after completion of the stenciling. 1n such case the link58 is shifted forward to the full line position of Fig. l and then atprinting operation the ribbon will be lifted to the a position in Fig.2, thus presenting the black field of the ribbon to the types andenabling the explanatory writing or other memoranda to be printed inblack on the stencil sheet. It will be observed that the variation inthe throw of the vibrator is effected by setting the link 58 andwithoutdisturbing the normal position of the operating lever 52.

. rier may be caused to engage at will with either the slot 84 or theslot 83 so as to obtain substantially the same results as were obtainedby the use of the single slot and the two cross pins in the priorconstruction. It will be noted that by my present invention I provide amember (in the present instance a lever) which member is combinedwith-means, for varying the normal position of the printing portion ofthe ribbon, said means in the'prcsent instance comprising a ribboncarrier or vibrator; that said member is also combined with means whichoperate to variably move the printing portion of the ribbon at printingoperation, this variable moving means comprising a link which issettable in a plurality of normal relationships with said member; thatsaid member has a single normal position;

that the ribbon carrier is connectible with said member at any one of aplurality of connecting points; that in the preferred form the ribboncarrier has a pluralityof cross pins which are connectible with aslotted operating lever; that the ribbon carrier and the operating leverare combined with means for affording a change in the normalrelationship between said carrier and said lever; that the operatinglever is connected with a key-operated universal bar by connectionswhich comprise a link; that means are provided for varying the normalrelationship of said connections or connecting devices, which meanscomprise a hand-operated controlling member having a plurality of faces;that said faces are adapted to co-act with a link; that the ribboncarrier is associated witha guide; that said caiiier may be vibratedindependently of said guide; that the guide may be moved to permit thenormal position of said carrier to be varied; that in the presentinstance this movement of said guide is a pivotal one; that when saidguide is turned on its pivot independently of the printing operation ofthe machine, said carrier is turnable with said guide; and that saidguide is spring controlled, the spring operating to restore it to normalposition after it has been given a pivotal movement.
